Comparison and multiresolution analysis of irregular meshes with appearance attributes
2004
We present in this dissertation a method to compare and to analyse irregular meshes with appearance attributes. First, we propose a mesh comparison method using a new attribute deviation metric. Considered meshes contain geometric and appearance attributes (e.g. color, texture,temperature). The proposed deviation assessment allows the computation of local attribute differences between two meshes. We present an application of this method to mesh simplification algorithm quality assessment.Then we propose two multiresolution analysis schemes for irregular meshes with appearance attributes. First, a mesh is decomposed in a discret number of levels of detail. We introduce a surface geometry rel…

Apparence des matériaux, Vision artificielle, Inspection qualité, Reflectance Transformation Imaging

Mastering the visual perception of the surfaces of manufactured products is a central issue for industry. However, in industry, the quality of surfaces is often assessed by human inspectors. Only a few specific cases use an instrumental or photometric approach. Among the photometric approaches, one of them is experiencing significant growth: Reflectance Transformation Imaging (RTI). However, this technique has limitations in terms of data acquisition and processing. The objective is therefore to correct some of these limitations in order to improve the RTI and, consequently, the visual quality control of surface conditions in industry.The current RTI systems are limited and cannot meet our …
Digitization and characterization of local reflectance of complex surfaces for visual inspection
2022
Mastering the visual perception of the surfaces of manufactured products is a central issue for industry. However, in industry, the quality of surfaces is often assessed by human inspectors. Only a few specific cases use an instrumental or photometric approach. Among the photometric approaches, one of them is experiencing significant growth: Reflectance Transformation Imaging (RTI). The RTI makes it possible to obtain a reduced and simplified estimate of the Bidirectional Reflectance Distribution Function (BRDF) and an estimate of the geometry of the surface. However, this technique has limitations in terms of data acquisition and processing. The objective is therefore to correct some of th…
Handicap et visibilité : de l’outrance involontaire du corps à l’outrance volontaire de l’apparence
2018
Comment passer outre par rapport a l’apparence ? Notre regard est souvent pris au piege de la difformite corporelle. Il impose a celui ou celle qui en est porteur le poids du rejet social. Loin de negliger l’etat de sideration produit par ce qui excede notre idee de l’humain, il faudra decrire phenomenologiquement cet obstacle du regard ; apres quoi seulement peut etre envisagee la dimension ethique de la reconnaissance d’autrui non pas malgre son apparence, mais a travers elle. La deformation corporelle genere une sorte d’outrance involontaire, une outrance definie comme ce qui deborde le regard, cree de l’incertitude quant a l’humanite meme d’autrui. Peut-on des lors retourner cette outra…

Costume and vestimentary device at the court of Philipp III of Burgundy from 1430 to 1455
2003
This study of vestimentary device at the court of burgundy from 1430 to 1455 leans on the systematic and computed analysis of the duke Philipp III of Burgundy's accounting. It turns towards five points : describing the terminology of costume and its written speech ; bringing nearer the vestimentary production and court activities, year by year, in relation with chroniclers accounts ; understanding the organisation of supplies based on humans reports (organisational chart, life of a garment, purveyors' tables) ; analysing rythms and levels of consummation, one by one, or in groups , with, in particular, a point about dress right at this time ; understanding the vestimentary personality of th…
